Chemical Experiments: Hauv kev sim tshuaj, cov iav kuaj cov raj yog cov hlab ntsha uas tseem ceeb. Lawv raug siv los tuav cov tshuaj reactants thiab saib xyuas cov txheej txheem thiab cov txiaj ntsig ntawm cov tshuaj tiv thaiv tshuaj lom neeg-xws li nag lossis daus, xim- hloov pauv kev sim, thiab ntau dua.
Kev sim tshuaj lom neeg: Cov iav kuaj cov raj kuj ua lub luag haujlwm tseem ceeb hauv kev tshawb fawb txog roj ntsha. Piv txwv li, hauv cov kev sim uas muaj cov kab mob microbial lossis cell kab lis kev cai, cov hlab ntsha sim muab qhov chaw zoo rau kev loj hlob thaum pab tus kws tshawb fawb soj ntsuam cov kab mob kev loj hlob thiab kev hloov pauv.
Kev Tshuaj Ntsuam Xyuas Kev Kho Mob: Hauv kev kho mob, cov iav tsom iav tau nquag siv rau kev sau thiab khaws cov qauv, xws li ntshav thiab zis. Lawv cov khoom sib khi zoo heev tiv thaiv cov qauv sib kis, yog li ua kom ntseeg tau qhov tseeb ntawm kev kuaj mob.
Kev Kawm Txuj Ci: Hauv thaj chaw ntawm kev kawm, cov kws qhia ntawv ntiav cov raj iav los ua qauv qhia txog ntau yam kev sim tshuaj, pab cov tub ntxhais kawm kom nkag siab ntau dua ntawm cov ntsiab lus thiab cov txheej txheem hauv qab cov tshuaj tiv thaiv.
Kev Tshawb Fawb Txog Kev Tshawb Fawb: Cov kws tshawb fawb tau koom nrog kev tsim cov ntaub ntawv tshiab thiab thev naus laus zis kuj tso siab rau cov iav tsom iav los ua ntau yam kev sim thiab kev sim.
Cov iav kuaj cov raj txaus siab rau daim ntawv thov thoob plaws ntau qhov chaw, suav nrog kev sim kev tshawb fawb, kev kuaj mob, kev qhia kev kawm, thiab kev tshawb fawb tshawb fawb. Lawv cov khoom muaj nyob hauv-xws li pob tshab, tiv thaiv tshav kub, thiab kev tiv thaiv siab- ua rau lawv muaj lub nkoj tsis tseem ceeb hauv chav kuaj.
